I'm trying to start a new rails app and for some reason my computer is no longer recognising rails....it's been working fine on every other rails app I've been working on until now.

When I typed;

rails new test_app -d postgresql -T

It threw up this error:

/home/camillavk/.rvm/gems/ruby-2.1.5/bin/rails:23:in `load': cannot load such file -- /home/camillavk/.rvm/gems/ruby-2.1.5/gems/rails-4.2.0/bin/rails (LoadError)
        from /home/camillavk/.rvm/gems/ruby-2.1.5/bin/rails:23:in `<main>'
        from /home/camillavk/.rvm/gems/ruby-2.1.5/bin/ruby_executable_hooks:15:in `eval'
        from /home/camillavk/.rvm/gems/ruby-2.1.5/bin/ruby_executable_hooks:15:in `<main>'

The same error is being thrown when I type rails -v. But when I type which rails I get 

/home/camillavk/.rvm/gems/ruby-2.1.5/bin/rails

I then tried to run gem install rails and all it says is 1 gem installed

Any ideas on why rails is doing this on my computer and how to fix it?

In case anyone else runs into this issue, I figured that rvm was just getting confused so I told it to use an older version of ruby

$ rvm use 1.9.3

THEN I ran rails new again. This time it worked so I changed into the new app, opened up the gemfile and in there told it to use the newer version of ruby again.

@camillavk,

Please see if the following rvm website link helps (make sure the info. included in these files mentioned in the article is accurate when you check them).

When I first started to use rvm, I used to have such issues as well so I am very careful to define all the rvm setup files for my rails projects.

  • but the link is talking only about project files...the problem is I cannot start a new Rails project at all... – camillavk Feb 13 '15 at 15:41

I just figured out a exactly the same problem and just used the following command:

gem uninstall -a

Which deletes all unnecessary gems. After that my environment worked well.
